    • Demonstration of vortex-induced beam shaping in seeded SHG 

      Molina Terriza, Gabriel; Minardi, Stefano; Bramati, Alberto; Di Trapani, Paolo; Torner Sabata, Lluís (2001-07)
      Article

      We report the experimental demonstration of a method that allows the simultaneous frequency-doubling and the shaping of a light beam into a variety of patterns. The technique is based on the controllable generation of ...
    • Evolution dynamics of discrete-continuous light bullets 

      Eilenberger, F.; Minardi, Stefano; Szameit, Alexander; Roepke, Ulrich; Kobelke, J.; Schuster, K.; Bartelt, H.; Nolte, Stefan; Torner Sabata, Lluís; LEDERER, FALK; Tünnermann, Andreas; Pertsch, T. (2011-07-29)
      Article

      We experimentally and numerically investigate the propagation of light bullets (LBs) excited in two-dimensional fiber arrays. The combination of nonlinear self-frequency shift, wavelength dependence of thedispersion, and ...
    • Soliton algebra by vortex beam splitting 

      Minardi, Stefano; Molina Terriza, Gabriel; Di Trapani, Paolo; Pérez Torres, Juan; Torner Sabata, Lluís (2001-07)
      Article
      Restricted access - publisher's policy
      We experimentally demonstrate the possibility of breaking up intense vortex light beams into stable and controllable sets of parametric solitons. We report observations performed in seeded second-harmonic generation, but ...
    • Three-dimensional light bullets in arrays of waveguides 

      Minardi, Stefano; Eilenberger, F.; Kartashov, Yaroslav V.; Szameit, Alexander; Röpke, U.; Kobelke, J.; Schuster, K.; Bartelt, H.; Nolte, Stefan; Torner Sabata, Lluís; LEDERER, FALK; Tünnermann, A.; Pertsch, T. (2010-12-20)
      Article

      We report the first experimental observation of three-dimensional light bullets, excited by femtosecond pulses in a system featuring quasi-instantaneous cubic nonlinearity and a periodic, transversally modulated refractive ...
